Analysis of Google’s Content Reading Level and Its Effect on SEO

As an SEO, I’m sure I look at the world in a slightly different way than most people. I see most things in terms of optimization; whether that is optimizing time, value, or Google rankings. I also am a very visual person, which in some regards is counter productive to analyzing traditional data.

Lucky for me Edward Tufte pioneered what today is known as an infographic, making it easy for visually minded people like myself to grasp large sets of data in a visual format and also help websites visualize their data sets for others to comprehend.

Reading Level Analysis

I recently came across a Google tool that defines the reading level of the content set of any website (and decided to create some charts and visuals based on the data) on the web and organizes the pages into 3 categories; Basic Reading Level, Intermediate Level, and Advanced Level.

Where Is The Google Reading Level Tool?

    1. First, do a site search in Google (our example will be so type in the search box
    2. Then click on the “show search tools” link in the left-hand navigation of Google (you might have to scroll down the page a bit depending on your screen resolution).


    1. This will open up the search tools option and give you the link to show “reading level” of the site you did the search for.

  1. Once you click on this you will see the image below (positioned above the search results) for the reading level of the pages on any site you do a “site:” for. I would make sure to check sites without the www to get all the content that lives on sub-domains of those sites as well.reading level result
  2. A user can also click on any of the reading levels to return a list of pages on the website that Google has defined as being at that reading level.

This Idea Of Reading Level Analysis Got Me Thinking

To get the chance to enroll in most colleges they require the applicant to have a certain ACT or SAT score or GPA. I thought, well if they require such levels of knowledge why not turn the mirror on some of the colleges work from their websites to see if they measure up.

So, what I did was find the top 10 colleges in the US (as outlined below) and analyzed the reading level of their sites (which included all areas of their website from the enrollment pages to the research studies published by some of their most intelligent professors and students) to determine if the people creating these sites and research on the sites live up to the high expectations the colleges require for their applicants.

The Top 10 Colleges

  1. Harvard University: Harvard University is a private institution in Cambridge, Mass., just outside of Boston. This Ivy League school is the oldest higher education institution in the country.
  2. Princeton University: The ivy-covered campus of Princeton University is located in the quiet town of Princeton, N.J.
  3. Yale University: Yale University, located in New Haven, Conn., offers a small college life with the resources of a major research institution.
  4. Columbia University: Columbia University has three undergraduate schools: Columbia College, The Fu Foundation School of Engineering and Applied Sciences (SEAS), and the School of General Studies.
  5. California Institute of Technology: The California Institute of Technology focuses on science and engineering education. The California Institute is actively involved in research projects with grants from NASA, the National Science Foundation, and the U.S. Department of Health and Human Services.
  6. Massachusetts Institute of Technology: Though the Massachusetts Institute of Technology located in Cambridge, Mass. may be best known for its math, science, and engineering education, this private research university also offers architecture, humanities, management, and social science programs.
  7. Stanford University: Stanford University is located in California’s Bay Area, about 30 miles from San Francisco. The private institution stresses a multidisciplinary combination of teaching, learning, and research, and students have many opportunities to get involved in research projects.
  8. University of Chicago: The University of Chicago, situated in Chicago’s Hyde Park community, offers a rich campus life in a big-city setting.
  9. University of Pennsylvania: Founded by Benjamin Franklin, the University of Pennsylvania is a private institution in Philadelphia, Pa. Undergraduates can study in four academic departments: Arts and Sciences, Nursing, Engineering and Applied Sciences, and Wharton.
  10. Duke University: Located in Durham, N.C., Duke University is a private institution that has liberal arts and engineering programs for undergraduates. The Duke Blue Devils sports teams have a fierce rivalry with the University of North Carolina—Chapel Hill Tar Heels.

An interesting point is that Columbia University is the most expensive of the top 10 with a 2011-2012 tuition of $45,290, yet has the least amount of advanced reading level material on its website.

Reading Level Analysis of Sites Labeled as Content Farms

I didn’t stop there, maybe because I was sitting at Argo Tea, slightly bored but mostly because I wanted to compare that data to another set of websites. So next I decided to take the same approach and analyzed the reading level of the top 10 content farms on the web. I chose the sites outlined below as my data set.

  1. Suite 101: The insight of 20000 writers, read by 35 million readers every month.
  2. Ehow: Learn how to do just about everything at eHow. Find expert advice along with How To videos and articles.
  3. All Experts: is the oldest & largest free Q&A service on the Internet.
  4. Wiki Q&A combined with free online dictionary, thesaurus, and encyclopedias. Ask questions, get answers.
  5. ArticleBase: Your free articles directory. Find free online articles for your website, eZine or newsletters.
  6. Associated Content: Associated Content has information on every topic.
  7. Buzzle: is a diverse research-based web portal, your complete source for news, articles, categorized information, and resources.
  8. Examiner: Get the latest news and articles on topics that interest you.
  9. EzineArticles: allows expert authors in hundreds of niche fields to get massive levels of exposure in exchange for the submission of their quality original content.
  10. Helium: Citizen journalism outlet offering a platform for writers to write articles on topics about which they are knowledgeable.

How did the “Expert’s” Content on These Websites Measure Up?

In short, not very well. Ehow was the best of the worst when it came to producing content that fell into that advanced reading level range at 25%, followed by Buzzle at 23%. The examiner was the worst of the worst having less than 1% of its content at an advanced reading level. Yet these sites still claim they hold high value when it comes to providing in-depth and useful information to their users.

College Websites vs Content Farms

Do we even have to do it? Yes, because it’s fun to create charts in Excel. If you compare the two types of content sets (the first being that of colleges and universities and the second being that of content farms), one can clearly see the value that the first holds and why the second holds little-to-no “expertise” or value.

So What Does Reading Level Mean for SEO?

In my opinion reading level is a clear indicator of the level of knowledge the writer has about a subject, thus an indicator to Google if the writer is an “expert” on the topic they are writing about. One of the primary SEO pitfalls that content farms seem to align with is the low reading level of their content. This is most likely due to the lack of expertise that most of their writers have about the topic they were writing about.

Moz’s panda questionnaire directly addresses content value and the focus on experts when it comes to creating valuable, research-based content. Google has stated many times that it wants to rank and present content to its users that is valuable and is research based, and not thin low quality content.
